改进了的光场—boson元激发非线性耦合的激光模型

在我们最近提出的光场Ｂ－ｂｏｓｏｎ元激发耦合激光模型的基础上，通过附加一个抽运系统的速率方程，将原先的激光动力学加以改进，以图整个系统的运作趋于更完备的远离平衡自组织。经过这样改动以后，改进后激光动力系统的速率方程组和描述光场与二能级原子相互作用的麦克斯韦－布洛赫方程组在形式上也有其更加相似之处；两者的自由变量与外控参量都有一一对应关系。

Revised Laser Model via Nonlinear Interaction of Light Field with Boson Elementary Excitation

The dynamics of lasing action via nonlinear interaction of light with boson elementary excitation is modified by an additional rate equation of pumping system which is directly coupled with the boson matter. After this modification the system as a whole becomes a more perfect self organization, but the mirrorless character essentially different from usual lasers is unchanged and the laser threshold behavior of second -order-like transition remains, too. The rate equation of the revised laser dynamics has some resemblance to Maxwell-Bloch eqnations for the coupling between light and two-level atoms.
